ToaZZ whom it may concern:

Be it known that I, Fnrnnnrcn donn Gr. MAISENHALDER, a citizen of the Unlted States, residing at Baltimore, in the city of Baltimore and State of Maryland, have invented certain new and useful Improve-- ments in a Sheet-Metal Building; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it appertains to make and use the same.

The object of the invention is to provlde a simple and comparatively inexpensive construction of sheet metal building adapted for manufacture in sections or units at a central distributing pointsuch as a factory and transportation to the point of use in condition .for assembling under such conditions as to minimize the risk of distortion or damage in transit; and furthermore to provide a construction of units or elements facilitating the assembling thereof without the employement of either a temporary or permanent frame work under such conditions as to insure a stable water proof structure capable of resisting the tendency of its own or applied weight or wind pressure to distort or disarrange the parts or members thereof, and moreover to provide a structure having a neat and ornamental appearance adapting it for use either as a garage or for dwelling purposes and either for temporary or permanent use; and with these objects in view the invention consists in a construction, combination and relation of parts of which a preferred embodiment is shown in the accompanying drawings, wherein:

Figure 1 is a side view, and

Figure 2 is an end view, partly broken away of a building embodying the lnvention.

Figure 3 is a detail sectional view of one of the wall panels or units.

Figure 4C is an enlarged detail section showing the joints between two wall panels or units.

Figure 5 is a sectional view similar to Figure 4 of the connected edges of two roof panels or units.

Figure 6 is a detail section of a corner anel or unit.

The wall and roof panels or units 10 and 11 are of similar construction and obviously may be made of any desired length to suit the dimensions of the proposed structure, and they are preferably made in stock widths as for example twenty-four inches (although obviously this may be varied at will), each panel or unit being provided with longitudinal oppositely, or inwardly and outwardly, directed ribs or offsets 12 andv 13 which are preferably cross sectionally angular as shown to represent for eX- ample one-half of a hexagon, to the end that the faces of each rib or corrugation are of equal width and the side faces converge toward the projecting or surface face which is parallel with the plane of the panel or unit.

T he corner` panels or units are preferably constructed to continuously span the angle of thestructure so as to present an unbroken surface, and to this end a blank such as is employed to form a wall section or unit is folded upon itself at its longitudinal center to form the angle 14, such a corner panel or unit being indicated at 15 and shown in detail in Fig. 6.

|1 he joints at the adjacent edges of the panels or units, which, contrary to the usual practice in the construction of sheet metal buildings, are no overlapped and hence are not open t0 the objection of involving a waste of wall material, are provided by forming triangular beads 16, directed inwardly at the edges of the panels or units, or the sheets constituting such panels or units, each bead having a wall 17 .perpendicular to the general plane of the panel or unit and a wall 18 disposed at an acute angle to the plane of the Wall 17 with its free edge terminating short of the plane of theY body portion of the sheet forming the panel or unit as indicated in Figures 4 and 5, the joints between the panels orV units of the side wall and roof corresponding in construction. rlhe triangular beads at the adjacent edges of twe panels or units are cross sec-tionally of right angled triat its longitudinal c`enter to form the acute angle, which however is preferably rounded as shown in Figures f1 and 5 with the extremities of the strip or blank folded inward to constitute the base of the triangle,- such base elements or flanges 21 being extended under the `free edges of the walls 18 of the beads 16 and terminating close to the perpendicular or altitude walls v17 of the said right angled triangular beads 16.

The effect of this construction of joint is to allow for the necessary movement to compensate for expansion and contraction incident to changes in temperature while affording a weather tight joint, elfectually preventingmoisture from gaining access to the interior of the wall or roof, and even` should moisture gain ac cess to the interiors of the beads, it is promptly removed therefrom by evaporation due to the fact that the beads are terminally open to permit of a free circulation of air therethrough. Furthermore, as indicated the joints are located in the cavities of the corrugations of the panels or units so as not to afford projections from the general plane of the wall of the structure. Both the beads and the caps by which they are engaged and which have an interlocking relation necessitating the application of the caps by longitudinal sliding movement, are of transversely yielding construction, or in other words are transversely capable of expansion and contraction, and due to the resilience of the material are capable of a yielding movement which insures a tight joint which however is adaptable to the strains applied thereto without involving the risk of disarrangement or permanent distortion.

Furthermore the described construction of bead is of advantage and'is preferred because of the fact that in the transportation of the panels or units fromthe factory to the place at which the building is to be erected, such beads are less likely to be distorted or bent and thus rendered inoperanaanoo? tive. They are adapted to yield to pressure without receiving permanent bend, owing to the fact that the edges of the walls thereof panels having beads with outwardly extending portions in contact with each other, inwardly extending angularly disposed pormentioned portions at the inner end, and a cap to intimately contact with and enclose said beads having inturned anges insertible beneath the inner edges of vthe second mentioned portions and in contact with the panels in advance of the lirst mentioned portions.

2. A joint construction for sheet metal building panels consisting of 'complemental panels having beads with outwardly extending portions in contact with each other, inwardly extending angularly disposed portions Ion said beads spaced from the rst mentioned portions at the inner end, and a cap to intimately contact with and enclose said beads having inturned flanges insertible beneath the inner edges of the second mentioned portions and in contact with the panels in advance of the first mentioned portions, said second mentioned portions terminating short of the panels to facilitate insertion of said flanges, and said langes terminating short of the rst mentioned portions;
